Infineon Technologies

Infineon Technologies with its unique position of being the only company currently offering silicon (Si), silicon carbide (SiC), insulated-gate bipolar transistor (IGBT) and gallium nitride (GaN) devices, is the customer’s first choice in all segments. Company offers one of the most comprehensive power portfolios in the industry ranging from ultra-low to high-voltage power devices.

ROHM Semiconductor

In 2021, ROHM is going to unveil new buck-boost battery chargers and USB PD controllers for mobile and portable products that reduce the required PCB footprint. Advanced process technology will also be utilized in 2021 by ROHM to deliver an expanded silicon carbide product line. The company’s 4th generation SiC MOSFETs use a double-trench structure on thinner SiC dies to drastically cut RDS (on). For high power systems, the increased current density on the MOSFET chip level will be coupled with soldering and silver-sintering compatibility on both sides of the SiC die to achieve significantly improved power cycling reliability and better thermal performance with flexible module packages.

Power Integrations

Power Integrations is participating in the rapid increase in the use of brushless DC (BLDC) motors. PI making very impressive improvements in inverter efficiency in three-phase applications, and meaningful system cost reduction using new single-phase motor drivers.

Brushless motors contribute to high efficiency, high-power density, good speed-torque characteristics, simple speed control and low acoustic noise, and are an excellent contributor to a high score for appliances targeting the new EU energy efficiency labelling scheme.


Looking forward to 2021, UnitedSiC is expanding its Generation 4 platform which has been introduced in early December 2020. The company has released this platform with Industry leading 0.7 mohm-cm^2 Rds-A at the 750V node. Also deploying these devices across additional voltage and package types. UnitedSiC is about to start the engagements providing higher levels of integration using our SiC FETs in integrated solutions that include integrated gate drivers, temperature sense, current sense, and slew rate control. These sophisticated products will simplify power supply design while reducing component count and easing initial design, all while providing more efficient, power dense designs.


In 2021, Transphorm intends to utilize the net proceeds to scale volume shipments of GaN products for the fast-charging power adapter, server, communication and gaming power supply markets as well as converters/inverters for industrial and renewable applications, expanded sampling and qualification in EV automotive applications, growth of its epi wafer business, as well as working capital to support general operations.
